Abstract
A number of 4-methyl-5-alkyl-5-α-methoxyethyl- and 2,2,4-trimethyl-5-α-methoxyethyl-1,3-dioxanes were synthesized. Precision rectification was used to isolate the individual stereoisomers, the configurations and preferred conformations of which were confirmed by IR and PMR spectroscopy. The reduction of the alkyl-α-methoxyethylacetoacetic esters, which gives the starting compounds for the synthesis of 1,3-dioxanes of 2-alkyl2-α-methoxyethylbutane-1, 3-diols, proceeds stereospecifically.
